MEANS FOR REENFORGING THE LOOK AND DOOR F TELEPHONE COIN COLLECTORS.

Application filed May 29, 1926. Serial No. 112,512.

This invention relates to compartments, U-shaped frame in the operated position and containers and the like and more particularly a dotted indication of its position when reto the coin box apparatus for pay station leased. 55 telephone sets. Fig. 2 is aside view of the cover cut 5 The principal object of this invention is to through at 2 of Fig. 1. 7

improve the construction of the locking cover Fig. 3 is a top view of the cover with a of compartments, containers and the like portion cut away to show the reenforcing such as those used with pay stationteleplate and the locking mechanism. 50 phone sets. The coin compartment cover consists of a Heretofore it has been the practice not to square piece of steel 1 the edges of which use hinges for coin box covers but to use are turned up and the corners rounded as an L-shaped lug riveted to the back of the shown in Figs. 1 and 2. Electrically welded door and extending below the bottom edge at spots to cover 1 is'a piece of strip steel 65 of the cover and engaging the bottom edge 2 which has its sides and center turned at 15 of the coin compartment for holding the right angles to the face as shown at? of Figs. cover in position. The top of the cover has 1 and These right angle vanes or fins are been held in position by the belt of a lock for reenforcing the L-shaped lug 8 at the which engages the upper edge of the coin bottom of plate'2. The upper center of the 70 box compartment. It is apparent that this piece of steel 2 is bent into a box shape as type of cover might be pried open. 7 shown at 13 of Fig. 3. A lock 17 is then According to this invention there is proplaced in this box and held by means of vided a cover having a reenforced L-shaped screws 5. Around the outer sides of lock 17 lug and a device for reenforcing the bolt of a U-shaped frame of steel 9 is mounted. 75 the lock. The L-shaped lug is reenforced by This frame has a strip 3 of lighter steel fins or vanes at right angles to its face and mounted across its arms and held by rivets also by being electrically welded to the back 11. Strip 3 is so mounted that it is in enof the cover. The lock is reenforced by a gagement with the bolt 6 of the lock and is I U-shaped frame which is carried upward held in this position by means of spring 4 so into engagement with the top of the coin box which is attached to frame 9 by rivet 10 and when the bolt is shot. is pressed against the bottom of lock 17. The device disclosing the invention com- When the cover 1 is placed in the coin box prises a cover of the coin box on which is compartment the L-shaped lug 8 which proelectrically welded a piece of steel having jects beyond the bottom of door 1 will enan L-shaped lug at the bottom of the cover gage the bottom of the opening in the coin 35 which closely engages the lower edge of the compartment asshown in Fig. 2. hen the coin box opening. This lug is reenforced bolt of lock 17 is shot the strip 3 carries the by means of right angle fins or vanes at its U-shaped frame 9 up into the position shown center and the outer edges. The upper part in Figs. 1 and 2 thus forming an auxiliary 90 of the piece of steel is formed into a box locking device at the top of the door. When 40 shape for holding the lock and a U-shaped the lock is released the bolt 6 drops back and frame around the lock which is so posispring t forces the frame 9 down into the tioned that it follows the bolt of the lock and position. shown by the dotted line 16 in engages the top edge of the coin box opening Fig. 1. i in conjunction with the bolt. This frame is When the door is locked in position its restored to its normal position by means of a lo e edge is against the lower outer edge 14' spring which draws it back when the lock is f th in Compartment d th l 8 i leleased- A more clear conceptlon y be against the lower inner edge. At the top the obtained of the objects and the operation of upper edo'e f th 1 i i t th upper 100 this invention from the following detailed Outer dg 12 f the oi o art ent and Fig. 1 shows a plan view of the coin box the upper inner edge as is shown in Fig. 2 cover disclos ng the lock cut away and the thereby guarding against an attempt to pry n, Ht

the door open. The edges of the coin box compartment have heen shaped as shown at 12 and LL of Fig. in order to protect the edges of cover 1 from the introduction of a prying tool.

What; is claimed is:

1. In eomhiImt-ion a compartment. a cover having, a plate secured thereto and a locking mechanism. said plate heine' shaped at one end to contain said locking mechanism and having an L-shaped lug formed at the opposite end thereof and reenforced with vanes formed at right; angles to its face, said lug arranged to engage the inner face of the compartment when the cover is in ene'anement with the outer face of said comipartmenttherehy 'lormine a seal.

2. In comhinat'ion a reccliitacle, a. cover having: a steel plate .-ftf't.titttl thereto, a locling mcchaniem haringaholt. said plate heine' shaped at one edge to contain said locking lllQtllHllifilll, and. a U shaped reent'orcing derice which is r: heed and lowered in conjunetion with said holt of said locking mechttlTiSlTl.

3. ln comhination a compartment. a ore.- harine a steel plate secured thereto. a loclting mechanism 1 string a holt. said plate hein; Shaped at one end to contain said loci:- ing mechanism. a U-shaped i'ramc around said locl-z and movahle with respect thereto. the holt of said lock carrying said U-shaped 't'rame upward into engagement with the inncr face of an edge of said compartment, said cover home in engagement with the outer face of the opposite edge of said compartment thereby forming a seal.

it. In comhination a receptarae. a cover having a steel plate securml thereto. said plate haringa reentorced L-shaped lug at one edge thereof and a housingat the opposite. edge thereof, a reent orced looking mechanism including a holt, mounted in said housing. said mechanism having a U-shapcd reent'orcine frame which is :arricd into cne ag'ement with the receptacle hy the holt of said mechanism. s: id lu; hiring so placed that it engages the inner face ol one end of said receptacle when said U-shaped 'l'ran'ie engages the inner "face ot the opposite end ol said receptacle simultaneously with the outer edge of the engagement of the over with the outer face of the receptacle thereby forming a se: l.

5. ln comhination. a compartment. a cover having a plate secured thereto. a locking mechanism including a holt, mounted on said plate. said plate having a housing. at one end for said locltin; mechanism. a.
